Hello, I need some advise on Emerald..I read that oiling is stable but not permanent. There are various type of oiling. So, when a vendor states oiled, do I need to ask if what type of oil is used? What does it mean by not permanent? Will oiling greatly reduce the price? what should I look out for when purchasing an oiled colombian emerald? Is a AIGS memo required? Greatly appreciate your help thks
